Conan O'Brien's show is in New York City all this week, and last night guest Hugh Jackman not only impersonated the host -- with the help of a mask -- he also showed Conan how to be more like George Clooney.

Jackman's Conan was helped by the donning of a mask, but he still does do a good version of Conan's "string dance" and monologue jump.

The 'Real Steel' star also showed Conan how to act more like George Clooney, which involves getting really really close to people. Watch Jackman's spot-on impersonations below.
